Emory University has won a patent fight with a defunct metro Atlanta biomedical firm and a former corporate officer who is now serving a federal prison sentence for securities fraud.

In an order handed down July 24, U.S. District Judge Thomas W. Thrash Jr. granted Emory’s motion for summary judgment in the case. In doing so, Thrash upheld patents that Emory has secured over the past decade for an anti-microbial agent impervious to water that can shield hard surfaces from contamination by weapons-grade biological viruses and bacteria.
